Nozzle Recognition Stickers

Labeling a Nozzle ID Sticker to a Nozzle

ACTION:

① From the surface to which the sticker is to be affixed, remove oil, dust and water content completely

using industrial alcohol.

② Pull out the shaft of the nozzle sticker tool approx. 3mm from the ring.

③ Peel the sticker from the paper using tweezers.

④ Place the sticker with its adhesive side up, and then put it in the jig (make sure that the D-cut on the

sticker is aligned with that on the ring). (The sticker must be angled so that the nozzle ID no. is

oriented as illustrated below.) Take care not to touch the adhesive surface with fingers.

⑤ Push the nozzle into the shaft. Make sure that the nozzle’s notch is aligned with the positioning slot on

the ring.

⑥ While pressing the nozzle’s rim, push the shaft into the ring so that the sticker is affixed onto the

nozzle.

⑦ Check that the sticker touches the bottom of the ring.

NOTE: If the shaft is pulled out of the ring too much, it may come off. If it comes off, align the shaft’s slot with the

ring’s positioning pin and then insert the shaft into the ring slowly.
